Description

Application data transmission method from the first device to the second device, and a data transmission system TECHNICAL FIELD OF TRANSFERRING APPLICATION DATA FROM A FIRST DEVICE TO A SECOND DEVICE, AND A DATA TRANSFER SYSTEM

The present invention relates to a method of transmitting application data from a first device to a second device, and a data transmission system.

The invention also relates to a device using application data and a memory device for intermediate storage of application data transferable using this data transfer method.

The invention also relates to a data transfer front end.

The use of electronic data has become part of everyday life. Most people are familiar with documents, music, videos, etc., which are available as electronic application data such as word documents, MP3 music files, MPEG movie files and the like. Many users of electronic devices, such as personal computers (PCs), portable music players, digital cameras, etc., also have the concept of copying application data from one device to another, for example word files from one PC to another. The concept of copying is used. Application data is often used for one or more devices, or for one or more types of devices. For example, an arbitrary word document that can be processed on any personal computer, an MP3 file that can be played on a personal computer as well as a portable music player, or a digital image file that can be created on a digital camera and transferred to a personal computer for image processing. Is provided.

There are various ways to transfer application data from one device to another. The simplest method is via a direct physical connection, for example an interface cable. However, if it is not possible to physically connect the two devices, for example if the devices are in different locations, the data is first stored from the data source device, intermediate storage such as a diskette, compact disk (CD), or memory stick. It can be copied to an intermediate storage media, the intermediate storage device can be brought to the target device, and then the data is copied. However, the memory capacity of the diskette is not very large, and writing to the diskette is typically very quite slow. In addition, diskettes can be easily damaged and data can be lost if the diskette is exposed to a magnetic field. Writing data to a CD (also called burning) is faster, but this can only be done once. Read / write CDs are available but expensive. Another common advantage of diskettes and CDs is that they are relatively large.

On the one hand, the use of memory sticks is widespread because they are small, convenient and fast. These memory sticks are also commonly referred to as "USB sticks", which interface to devices such as personal computers with a universal serial bus (USB) interface. Their reputation is mainly due to the ease of use and the practical possibilities offered by the USB type interface. Personal computers typically have only a single diskette or compact disk drive, while they easily have multiple USB slots or USB hubs so that the memory stick can simply be inserted into a free slot. Other small devices that generate or provide application data, such as digital cameras or portable music players, are often equipped with a USB interface that coffees data to or from the device. Thus, the reputation of memory sticks, such as intermediate storage devices, is expected to increase further.

However, the use of memory sticks to transfer data from one device to another does not completely rule out defects common to all modern intermediate storage media. For a user who often transfers data between devices, for each data transfer he inserts his memory stick into a USB slot (not always easily accessible), copies the data to the stick, and copies the memory stick to the USB. There is an obvious flaw that the processing at the target device has to be repeated in order to remove it from the memory stick and transfer data from the memory stick to the target device. In addition, when the memory stick is used to transfer data to a number of different destinations, the user uses, for example, Windows Explorer to select the files intended for each destination device for each transfer. You should examine the contents of the memory stick. Another drawback is that these compact and compact memory sticks can easily be lost to the device's USB interface.

It is therefore an object of the present invention to provide an easy and convenient method of transferring data from a source device to a target device while avoiding the problems described above.

For this purpose, the present invention provides a method for transmitting application data from a first device to a second device, the method comprising a user touching a touch interface of the first device, the user touching the device. While doing so, the connection-related data is exchanged through the user's body between the first device and the memory device. The memory device is thereby carried in a person who is a user, for example in a pocket. Based on the connection-related data, a connection exchanging application data is established between the first device and the memory device. Application data is subsequently transferred from the first device to the memory device via this connection and then stored in the memory of the memory device.

In the following, the term “touch” is used to describe the contact made between the user and the source or target device. There must be a contact so that connection-related data can be exchanged between the device being touched and the memory device held by the user's body. The nature of the contact or touch depends on the implementation of the touch interface of the device, so that one type of device requires the user to maintain the contact for the duration of the exchange if, for example, the fingertip or the thumb presses the touchable area. . Touch interfaces of other types of devices are implemented such that the user only needs to approach it with his fingertips for the connection-related data being exchanged, ie no physical contact is required. The pre-requisite is that he must bring his fingertips very close to the touch interface so that the area he points to can be determined by the touch interface. The sensitivity of the touch interface is configured to respond only if the user is surely in contact with the area of the touch interface, and not to react if the user touches over the touch interface but is at a distance from the touch interface.

In the next step, the user touches the touch interface of the second device and the connection-related data is exchanged between the memory device and the second device through the user's body, so that the connection exchanging application data is based on the connection-related data. It is established between the device and the second device. As a result, at least some of the application data is transferred from the memory of the memory device to the second device via the connection. Transfer of application data to and from the memory device can occur through the user's body or through an established connection between the memory device and the first or second device.

The memory device according to the invention used for intermediate storage of application data in a transfer from a first device to a second device comprises a connection interface for exchanging connection-related parameters with a first or second device via a user's body. . Such an interface may include a transceiver for human-coupled communication (BCC). Recently, as described, for example, in "Personal Area Networks: Near-field Intra-Body Communication (T. Zimmerman, IBM Systems Journal, Vol. 35, Nos 3 & 4, 1996)". There have been significant advances in the field of data transmission. Those skilled in the art will be familiar with the essential techniques that do not need to be described in more detail.

In order to receive application data from the first device and to transfer the application data to the second device, the memory device is preferably adapted to operate to transmit the application data over a connection established using previously exchanged connection-related parameters. It includes a data transmission arrangement. In addition, the memory device preferably comprises a memory module or unit for storing application data. Due to this function, the memory device is also referred to as "data carrier" or "intermediate storage device" hereinafter.

The first and second devices referred to herein may be any kind of electronic device that processes application data, such as a personal computer, home entertainment device, personal digital assistant (PDA), portable music player, or the like. In the following, for the sake of simplicity, the first device and the second devices will be referred to as "source device" and "target device" respectively. Obviously, the device may be mounted to operate as a source device when transmitting application data to the memory device and as a target device when receiving application data from the memory device. In order to be able to transfer application data to or from a memory device, such a source or target device may also be based on connection-related data and the necessary touch and connection interface combinations for exchanging connection-related data between the device and the memory device. A data transmission device, for example a suitable transceiver, which transmits application data over an established connection must be used. The touch interface and connection interface combination may be a single module or may include two separate or separate modules that never operate in conjunction with each other. "Application data" may be any file or any document in any format, for example a word file, an image file, a PDF file, an MPEG file, an executable file, and the like, referred to hereinafter simply as "file" or "files." Can be. The touch interface and connection interface combinations as well as the data transmission device may be integrated into the device or may be integrated into an external data transmission front end connected to the device, as described below.

A suitable data transfer system for transferring application data between a first device and a second device includes a memory device for transferring to a user person, the memory device comprising a memory for intermediate storage of application data and a device via the user's body. And a connection interface for exchanging connection-related data, and a data transmission device for receiving application data from the first device and transmitting application data to the second device through an established connection based on the connection-related data. When assigned to the first device, the data transfer system establishes a connection established with the touch interface and the connection interface for exchanging connection-related data between the first device and the memory device through the user's body, and based on the connection-related data. And a data transmission device for transmitting application data from the first device to the memory device. Similarly, when assigned to a second device, the data transfer system is based on a touch interface and connection interface coupling that exchanges connection-related data between the second device and the memory device through a user's body, and based on the connection-related data. And a data transfer device for transferring application data from the memory device to the second device through the established connection.

The method according to the invention is particularly preferred because the data transfer is initiated by a simple touch operation of part of the user. This "just touch" interaction of exchanging network parameters using the human body as a signal transmission medium is very simple and completely intuitive to use. Another obvious advantage of the method according to the invention is that the user does not need to physically connect the memory device itself to an interface socket of one of the source or target devices since the application data is transmitted wirelessly to and from the memory device. . Data transfer is carried out in a comfortable, intuitive and easy way. Since the user can carry the memory device in his, for example, jacket or pants pocket, he avoids the effort of inserting the memory device into the interface of the first or second devices. In addition, since the memory device remains in the person who is the user, it is not left in the device interface.

The dependent claims and the following detailed description describe particularly preferred embodiments and features of the invention.

As mentioned above, recent years of technological advances in the field of in-body communication (eg, data transmission through a human body) have enabled data to be successfully transferred from a source device to a destination device using the human body as a carrier. In general, it is inherently possible to transfer application data between a memory device and a source or target device via a user's body via an established connection based on connection-related data already exchanged through the user's body.

On the other hand, due to obvious limitations, the human body is not very suitable for data transmission at high power or high frequencies. However, as long as the user maintains physical contact with the source device, data can be transmitted at low frequencies and at low power. Thus, since a relatively small amount of data is exchanged within a short time, the method according to the invention only transmits connection-related data through the user's body.

Moreover, in particular in the preferred embodiment of the present invention, once the connection-related parameters are exchanged, a wireless high frequency network is established between the corresponding source or target device and the memory device using these parameters. This procedure is described as a suitable standard and involves the exchange of "combined" and "accepted" requests with which the transceivers can recognize predefined signals or messages, for example device addresses. Such procedures and standards are well known to those skilled in the art. Once the network has been successfully established, application data can be transferred between the memory device and the source or target device via a wireless radio connection. During the transmission of the application data, the user must remain within the transceivers range. Transmission completion is indicated by an audible or audible signal such as a beep or flash LED (light emitting diode).

Various standards are established in wireless high frequency communications over short distances, such as the IEEE 802.1 (wireless LAN) and IEEE 802.15 (wireless PAN) standards. A network of devices (usually several meters away) that is adjacent to a person is called a Personal Area Network, or PAN. If this communicates in a wireless manner, the network is referred to as a wireless PAN, or WPAN. Several network technologies have been developed for wireless personal area networks. One of the best known is Bluetooth and it is possible for different devices to communicate with each other. Another recent technology is the ZigBee standard, which can be simpler to implement and allows the implementation of lower cost devices.

For mutual wireless communication, two or more devices need to obtain network- or connection-related data, such as a radio channel frequency, that exchanges data, network identifiers (IDs), device addresses of each of the devices, and the like. As mentioned above, in the method according to the invention, these network parameters are exchanged by capacitive coupling of lowest (pico-amperes) currents through the body of the user, for example through the body, using intrabody signaling. This is achieved when the user, for example, touches the touchable area of the touch interface of the source or target device with his finger-tip to maintain contact with the touchable area for the duration of the exchange. The touch interface of the source / target device may be, for example, a dedicated area of the display, a keyboard, or another area of the device, a button, a touch pad, or the like. If the amount of data required to characterize the connection is relatively small, then the exchange duration and the contact duration of the user and source / target device may be short correspondingly. Once the network parameters are exchanged between the source or target device and the memory device through the user's body, the user can interrupt the contact, for example by removing his finger-tip from the device's touch interface.

While the network parameters are exchanged between the device and the memory device, the type of contact that the user makes with the device may have information on its own about the transfer direction or transfer type that should be performed. For example, a "copy" type transfer indicates a transfer from a source device to a memory device. On the other hand, a "paste" type transfer indicates a transfer from a memory device to a target device. These functions are well known to any user of a personal computer or similar device and are used as clipboard functions in most all applications that process data such as word processors, image processing applications and the like. In addition, when the touch interface includes dedicated areas for different types of transfers—copy, paste, movement—information that the user touches may be analyzed by the touch interface to determine the transfer direction and type. Alternatively, for a simpler implementation, the user touches the touch interface 1 time to indicate coffee transfer, 2 times for paste transfer, and 3 times for transfer transfer. For example, the user may choose to move the touch interface to indicate that the selected file should be moved, that is, first copied to the memory device and then deleted from the source device before holding his finger pressing the touch interface so that network parameters can be exchanged. Tap three times. Suitable circuitry or detectors are integrated into the touch interface to detect different types of touch sequences made by the user. In addition, while the connection parameters are exchanged, the user can " write " his fingertips on the touch interface, for example by dragging his fingertips in the form of " C " It can also be thought that.

Thus, in a preferred embodiment of the present invention, the touch interface of the source or target device may include a corresponding number of unique application data transfer types between the device and the memory device—eg, "copy", "paste", and / or " A plurality of touchable areas for "move". Alternatively, the touch interface includes a suitable detection unit that detects a contact type or sequence made by the user in the touch interface to determine which of the various transmission types is indicated by the user. In one relatively simple embodiment of the present invention, any selected files or currently open or working files are automatically stored in the memory device when the user touches the touchable "copy" or "move" area of the device's touch interface. All data currently stored in the memory device may be transmitted to the device when the user touches the touchable "paste" area of the device's touch interface. In this kind of embodiment, the memory device acts as a simple "clipboard", the function of which is well known to any user of a personal computer.

As already mentioned, the application data sent from the source device to the memory device may have one or more target devices as destinations. For example, a single file is intended for one or more target devices. Alternatively, one file is intended for the first target device and another file is intended for the second target device. One of the advantages of the present invention is that application data can be automatically transferred to the intended target device without the user searching the contents of the memory device to select a file for transfer to a suitable target device. In a very preferred embodiment of the present invention, a label specifying certain transmission parameters or conditions is generated for the application data, which label is transmitted with the application data to the memory device. For example, before application data is sent to the memory device, a label can be generated at the time the user selects a file at the source device. The label may specify the target device for which the file is intended and facilitates the user to copy, paste, or move different files transferred from the source device to the memory device in a single session to a number of different target devices. For example, a user may use a portable music player as a target intended for selection of music files, his car stereo as a target intended for the same or other music files, and a home entertainment system as a target intended for a video file. You can designate another PC as a spreadsheet or text documents. Then he can transfer all the files to his memory device in one session. Thereafter, by simply touching the touch interfaces of the target devices in turn, the application data intended for the relevant target device will be automatically transmitted. Needless to say, the target devices can be placed anywhere, and the user can achieve data transfer from the memory device to one of the target devices at any convenient time when near the target device.

The label may also specify the lifetime of the file to the intended target device or memory device. After this lifetime expiration, the application data is automatically marked invalid. The label also specifies a number of times the file is transferred from the memory device to the target device. Software suitable for the source device may, for example, allow automatic generation of labels for files stored by the user in any folders of the computer's file management system. For example, when a user moves or drops a music file to a folder called "music for player," the software labels the file corresponding to the portable music player as the target device. Will be generated automatically. It is also understood that a user may specify a destination by saying a destination, for example by clicking on a music file icon to indicate the destination of the file and saying "player".

It is preferred that the memory device according to the invention be carried by a person who is a user. However, one preferred type of implementation combines one or more such devices with a memory device, since most users of application data already have one or more portable devices with them, such as PDAs, mobile phones, and the like. For example, there is a mobile telephone incorporating an embedded memory device according to the present invention.

The memory device according to the invention does not need to be physically connected to the data interface of the source or target device in order to transmit application data since network-related parameters are exchanged through the body of the user. However, not all devices are equipped with means to communicate with memory devices using in-body combined communication. To allow this ending, the memory device may also be implemented with an interface connector such as a USB connector so that the memory device is also obtained from or intended for such a device by directly inserting the memory device into the device's interface socket. It can be used for intermediate data storage for the generated application data.

In order to allow easy upgrade of source or target devices that do not have a touch interface, the present invention also describes a data transfer front end to an interface between such a device and a memory device. This front end is a portable module that can simply be connected to the device using one of the available device interfaces, for example a USB port or a serial port. Once the front end is connected to the device, data transfer between the device and the memory device may occur in the manner already described above as described above. To this end, the data transfer front end includes a touch interface and connection interface combination such that connection-related data or parameters can be exchanged between the device and the memory device. The front end also transfers application data from the device to the data transfer front end using a connection established based on connection-related data, i.e., downloading files from a device, or uploading files to a device. It includes. In order to transfer application data between the data transfer front end and the memory device, the front end also includes a data transfer apparatus capable of exchanging application data with the memory device. With the help of this data transfer front end, a device which does not use the required interface can be used as a source or target device in the data transfer system according to the invention.

Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings.

However, the memory device 1 can be carried at any convenient location of the person who is the user 2 and can be, for example, embedded in a shoe, attached to a belt or embedded therein. For purposes of explanation, the user 2 is shown as being in the vicinity of all devices D, D _S , D _T1 , D _T2 , but as described below, the data transfer is performed by the memory device 1 and the single device D, It will be appreciated that it may occur between D _S , D _T1 , DT _T2 ). Using the method according to the invention, the user 2 allows the wireless radio connection or network to simply touch any of the devices D, D _S , D _T1 , D _T2 included in the network. ) And one or more of the devices D, D _S , D _T1 , D _T2 . Each of the devices D, D _S , D _T1 , D _T2 utilizes a suitable interface 3, 3 ′, 3 ″, which will be described in more detail below, through which network-related data is transferred to the devices D, D _S , D _T1 , DT _T2 ) and the memory device 1 can be exchanged.

In the preferred method described above in detail, data is transferred between the device and the memory device by the user first touching the device so that the network-related parameters of the wireless high frequency network can be exchanged between the device and the memory device, and then the network- Application data may be transmitted over a wireless radio network established using the relevant parameters.

The device and memory device need to have the necessary units and modules to perform these steps shown in FIG. Here, in the data transmission system 20, a device using a front end 3, a user interface 200 (eg, a keyboard, a mouse, a graphical user interface), a memory 201, and a processor 202 (D _S). ) Is shown. Other modules or units that are typically integrated in such a device but are not necessary for the invention are not shown in the figures. The data transfer system 20 also includes a memory device 1 and target devices D _T1 , D _T2 . And including a source device (D _S) and the target device (D _T1, D _T2) Both the touch of the display of the corresponding device region, or any buttons of the device, the area of the device housing, the device (D _S, D _T1 , D _T2 ) utilizes touch interface and connection interface combinations 215 and 235 that can be executed differently for each. Here, the touch interface 210 of the source device D _S is divided into three separate touchable areas 210 _C , 210 _P and 210 _M— “copy” area 210 _C , and “paste” area 210 _P. ) And "move" region 210 _M )-. In the touch interface 230 of the target device D _T2 , the user may use only the paste region 230 _P. The touch interface and contact interface combinations 215 and 235 detect the type of touch made by the user, determine the corresponding type of execution transfer, and send a wake-up signal to the memory device 1. present.

In order to select the application data for transfer, the user is presented with a graphical user interface 200 of device D _S for example representing a file F _{1 to} be stored in memory 201 and transmitted to memory device 1. It is available. Here, the user indicates that the file F ₁ will be transmitted to the target device D _T. Prior to this, at any suitable time, the software program operating at the source device D _S generates a corresponding label L ₁ indicating the device D _T1 as a destination, and the file F ₁ indicated by dotted lines in the figure. Link any of the labels L _{1 in a} suitable form.

When the user touches the touch interface 210 on the front end (3) of the device (D _S), the touch interface 210 may cause the electrical circuit BCC transceiver 221 of the memory device 1 and the device (D _S Notify the BCC transceiver 211 which in turn is closed between the BCC transceivers 211, through which the circuit network parameters 4 are at the lowest current (typically indicated by arrows shaded to the social parallel lines in the figure). In the region of pico-amperes). Once the network parameters 4 have been successfully exchanged, the user may stop contacting the touch interface 210 of the front end 3, which may be a dial tone, chime, visible signal, or processor 213 to the user. Are transmitted in any other suitable type of signal generated by the software 214, which may be recognized by the user.

The network parameters 4 exchanged between the device D _S and the memory device 1 are transmitted to their respective radio frequency transceivers 212, 222, which then receive the front end transceiver 212 and the memory device transceiver ( A wireless radio network N between the device _DS and the memory device 1 indicated by a white arrow is set between 222.

Once the wireless radio network (N) that when made, the file (F ₁₎ with its attached label (L ₁₎ are retrieved from the memory 201 of the device (D _S), the radio frequency front end (3) transceiver Transmitted via network N by 212. Security issues may be considered in transmission by having the application data encrypted or encoded in a proper manner prior to transmission so that only memory devices can decrypt or decrypt the data. The radio frequency transceiver 222 of the memory device 1 detects the transmitted signal and labels the copy F ′ ₁ of the application data F ₁ received in the memory 220 of the memory device 1. ₁ ) with a copy of L ' ₁ ). Thus, the "copy" transmission is completed, and then the wireless network N can be interrupted. The software 224 may be coupled with the processor 223 of the memory device 1 and analyzes the label L ₁ ′ to determine the device as to whether the received data F ′ ₁ is intended.

In order to transfer the application data F ′ ₁ from the memory device 1 to the target devices D _T1 , D _T2 , the user has to touch the touch interface of the front end 3 ′ of the target devices D _T1 , D _T2 . In operation 230, the corresponding “paste” area may be touched. In the essentially the same method described above, network parameters are exchanged between the BCC transceiver 221 of the memory device 1 and the BCC transceiver 231 of the front end 3 'of the target device (D _T1 , D _T2 ). , Allowing each radio frequency transceiver 222, 232 to establish a radio frequency network, and is essentially the same as described above, although not shown in the figure.The processor 233 is a target device D _T1 , D _T2. A request is made to the memory device 1 with respect to the software 234, and requests the data it has for the target device D _T1 , based on the label L ' ₁ , the memory device 1 data (F sends a _"1) the target device (D _T1, D _T2) whether the wireless radio network file (F via whether intended for a" ₁₎ the radio frequency signal is a target device (D _T1, the front of the D _T2) Is picked up by the RF transceiver 232 of de (3 '), data that incoming is "is stored as _(1. Accordingly, the copy F)" of the original file (F ₁₎ in the memory 241, the paste "transmission completion And the wireless network may be interrupted.

In FIG. 3A, the memory device 1 is a standalone intermediate data storage device and can be used to transfer data between the source or target devices D _S , D _T1 , D _T2 . In this figure, it is assumed that the source or target devices D _S , D _T1 , D _{T2 each} have a built-in front end with a touch interface, a connection interface, a wireless radio transceiver, and the like, as described above.

3C shows the implementation for the case where the device D does not use the touch interface or the connection interface. In this example, using the USB connector 32, the front end module 3 "can be inserted into the USB interface 33 of the device D, which causes the application data to be stored using the method according to the invention. To allow transmission between device 1 and device D. FIG.

In the case of using a device D that is not equipped with a wireless radio transceiver, the memory device 1 can be implemented using a suitable data transfer interface as shown in FIG. 3D. Here, the memory device 1 is executed as a memory stick 34 having a USB interface connector 32, and thus the USB stick 34 for transferring data to or from the device D for which wireless data transfer is not possible. Can be simply used.

The sequence of the figures shown in FIGS. 4A-4K shows a user 2 for transmitting application data F ₁ , F ₂ from a source device D _S to two separate target devices D _T1 , D _T2 . The steps taken by will be described. In the drawings, for purposes of explanation, the devices D _S , D _T1 , D _{T2 are} shown in simplified form and shown in close proximity. In essence, the devices D _S , D _T1 , D _T2 are any of the devices mentioned in the previous description, for example a portable music player, a home entertainment device, a car stereo, a personal computer, a satellite receiver, any electrical device. And the like. In addition, the source device D _S may be at a distance from the target devices D _S , D _T1 , and D _T2 . For clarity, the touch interfaces 210, 230 of the devices D _S , D _T1 , D _T2 are not shown in detail, and are simply indicated by dashed lines. The file stored in the memory of the devices D _S , D _T1 , D _T2 is simply indicated by the usual file code.

In FIG. 4A, the user 2 is shown having his wireless memory stick 1 in the pocket of his jacket. He wants to copy two files F ₁ , F ₂ from the source device D _S. The user 2 can display the desired files F ₁ , F ₂ , which are copied in any suitable manner, such as clicking them with a mouse not shown in the figure. In addition, the user 2 specifies the destination device for each of the files F ₁ , F ₂ he wishes to copy. In this example, the first file F ₁ is copied to the first target device D _T1 , and the second file F ₂ is copied to another second target device D _T2 . In order to ensure that the files F ₁ , F ₂ are copied to their exact intended destinations, the source device D _S generates a first label for the first file F ₁ , and the second file For F ₂ , a second label is generated. For clarity, the labels are not shown in the figure.

User touches the "copy" button on the touch interface 210 of the source device (D _S). When attempted by that event, the connection interface of the source device D _S wakes up the BCC-transceiver and instructs it to broadcast or transmit the wake-up signal via in-body coupled communication. The BCC transceiver of the memory device 1 wakes up by receiving a wake-up signal via in-body coupling communication, indicated by arrows shaded on the social parallel lines in FIG. 4B. The BCC transceivers of the memory device 1 and the source device exchange network parameters 4 (ie, wireless channel, network ID) via in-body coupled communication. The user 2 can now remove the fingertip from the touch interface 210 of the source device D _S. Time he lifts a finger tip on the touch interface 210 may be represented by tone dial tone to be presented by the source device (D _S). The control software of the memory device 1 and the source device D _S instructs their RF-transceivers to join the wireless radio network specified by the radio channel and network ID.

In Figure 4c, a wireless radio connection is established between the memory device (1) and the source device (D _S), it is shown in bold white arrow. The connection interface transfers copies of the files F ₁ , F ₂ to which corresponding labels are attached via its RF transceiver from the source device D _S to the RF transceiver of the memory device 1. The memory device 1 subsequently stores the data which enters its memory.

Once copies of the file F ₁ , F ₂ with labels are transferred from the source device D _S to the memory device 1, the connection interface of the source device D _S leaves its wireless connection and its RF Stop the transceiver. Similarly, memory device 1 instructs its RF transceiver to interrupt the network. This is indicated by, for example, an audible dial tone or a viewable signal. The user 2 approaches the target device D _T1 shown in FIG. 4D and touches the “paste” button of the touch interface 230 of the target device D _T1 .

In the same manner as described above, the target device D _T1 wakes up the memory device 1 via in-body coupled communication, indicated by arrows shaded in the social parallel lines in FIG. 4E. The memory device 1 designates the connection parameters 4 for a new wireless radio connection and passes these in-body coupled communication to the connection interface of the target device D _T1 via the body of the user 2. Transmits 4. Once this transfer is complete, the user 2 may release the touch interface 230 of the target device D _T1 .

As shown in FIG. 4F, the first target device D _T1 joins the wireless network indicated by the thick white arrow set by the memory device 1. The first target device D _T1 then requests the memory device 1 to transmit any data stored in its memory intended for this target device D _T1 . Upon receiving this request, the memory device 1 starts to transmit its copy of the first file F ₁ to the first target device D _T1 as data via a wireless connection. The first target device D _T1 starts storing data in its memory as a copy F ₁ ′ of the original file F ₁ .

The second to transmit a copy of the target device (D _T2), the second file (F _2), as shown in Figure 4g, the user 2 can go up to a second target device (D _T2), the target Touch the "paste" button of the touch interface 230 of the device D _T2 . On the other hand, the memory device 1 is still transmitting data to the first target device D _T1 indicated by the file code shown by the dotted line.

In the manner already described, the second target device D _T2 wakes up the memory device 1 via in-body coupled communication, indicated by thick black arrows in FIG. 4H. Since the memory device 1 has already established a wireless radio connection, it immediately sends the required network connection parameters 4 to the second target device D _T2 using in vivo combined communication. The user 2 can now release the second target device D _T2 .

As shown in FIG. 4I, the second target device D _T2 joins the wireless radio network established by the memory device 1. Both the target devices D _T1 , D _T2 and the memory device 1 are now part of the same wireless high frequency network, indicated by thick white arrows. The second target device D _T2 requests the memory device 1 to transmit any data intended for it. On receiving this request, the memory device 1 examines the labels of the received files and subsequently sends a copy of the second file F ₂ to the second target device D _T2 via a wireless RF connection. The second target device D _T2 starts to store the received data as a copy F ′ ₂ of the original file F ₂ in its memory.

Once the first target device D _T1 has finished receiving all its requested data, as shown in FIG. 4J, the connection interface instructs its RF transceiver to leave the network and stop. In the same way, when the second target device D _T2 receives all of its requested data, as shown in FIG. 4K, its connection interface instructs the RF transceiver to leave the network and stop. As a result, the control software of the memory device 1 instructs its RF transceivers to close the network. The original file (F _1, F ₂₎ is copied to the source device (D _S) of the target device (D _T1) intended. In essence, the user can copy any number of different files from either the source devices D _S to the target devices D _T1 , D _T2 . When a file is transferred from the memory device 1 to its intended target destination, a copy of the file can be deleted from the memory device 1.

5 illustrates the different steps of the data transfer procedure described in FIGS. 4A-4K in the form of a message sequence chart. The timeline is each of the user 2 and the devices 1, D _S , D _T1 , D _{T2 included} , that is, the memory device 1, the source device D _S , and the two target devices D _T1 , D _T2. ) Is shown. Communication, messages, or data transmissions from a user to one of the devices or from one device to another are indicated by arrows in the appropriate direction. Thick vertical bars along the timeline indicate the duration of the corresponding phase or data exchange.

"Copy" button on the touch interface, in this case - - In a first step 1 Ⅰ, the user touches the interface of the source device (D _S), if a touch, BCC transceiver of the source device wake the BCC transceiver of the memory device (1) -Up signal. This causes the memory device 1 to set up the network and to exchange the necessary parameters 4-in this case the channel number and ID-with the source device through the body of the user 2. If the parameters 4 are exchanged, the user 2 can release the touch interface and the wireless radio network is established using the connection parameters 4.

In the next step II, the RF transceiver of the source device D _S presents a join request to the RF transceiver of the memory device 1, which in turn presents an acceptance. Once the devices 1, D _S have joined the network in this manner, the application data can be copied from the source device to the memory device in the copy procedure C _1,2 . Once the copy procedure C _1,2 is complete, the source device D _S presents a leave request to the memory device and stops its RF transceiver. The memory device 1 in turn stops its RF transceiver. The network no longer works.

In the following step III, the user approaches the first target device D _T1 and touches the “paste” button on the touch interface of the device. The BCC transceiver of the first target device D _T1 presents a wake-up signal to the BCC transceiver of the memory device 1. This causes the memory device 1 to set up the network and exchange the necessary parameters 4 with the first target device D _T1 through the body of the user 2. When the parameters 4 are exchanged, the user 2 can release the touch interface and the wireless radio network uses the connection parameters 4 to connect the memory device 1 and the first target device D _T1 . Is established between.

Next, in step IV, the RF transceiver of the first target device D _T1 presents a join request to the RF transceiver of the memory device 1, which in turn presents an accept. If both devices 1, D _T1 join a new network, application data may be copied in a paste transfer P ₁ from memory device 1 to a first target device D _T1 .

During this paste transfer P ₁ , the user decides to transfer the intended data for the second target device D _T2 . For this reason, in step V, the user touches the "paste" button on the touch interface of the second target device D _T2 . The BCC transceiver of the second target device D _T2 presents a wake up signal to the BCC transceiver of the memory device 1. As a result, the memory device 1 provides the second target device D _T2 with the parameters 4 for the existing network through the body of the user 2. If the network parameters 4 have been exchanged, the user 2 can release the touch interface, and the second target device D _T2 is in step VI the memory device 1 and the first target device D _T1 . It is possible to join an existing wireless radio network that has already been set up in between, and the data request when the memory device 1 starts to transfer the intended data to the second target device D _T2 in the paste transfer procedure P ₂ . To present.

Upon completion of the paste transfer procedure P ₁ , P ₂ , the corresponding RF transceiver may present a rib or stop request, such that the RF transceivers of the first and second target devices D _T1 , D _T2 are stopped and ultimately There is no network.

As mentioned above, networks required for data transfer between a memory device and a source or target device should rather exist as long as they are needed to transfer the actual data. The network can then be shut down. As a result, devices using this type of data transmission are characterized by significantly lower power consumption.
